From 0cc87b3baceedd05208464f7fc7b5157bd618505 Mon Sep 17 00:00:00 2001 From: Tomasz Maciej Nowak Date: Fri, 23 Aug 2019 15:50:52 +0200 Subject: ath79: image: disable sysupgrade images for routerstations and ja76pf2 Because a bug in handling partial erase blocks in 4.19 kernel, using sysupgrade images will hard brick devices that use RedBoot bootloader and have "FIS directory" with "RedBoot config" on the same erase block. Since flashing the devices from bootloader is safe, and to not cause a situation where external chip programmer or JTAG is needed, disable sysupgrade images for affected boards while creating kernel.bin and rootfs.bin for jjPlus JA76PF2 board, which doesn't have factory image. To set up the JA76PF2 board follow "Installation" instructions in b3a0c97 ("ath79: add support for jjPlus JA76PF2") except the part of loading initramfs image and using sysupgrade image for flashing (point 6 and 7). Enter following commands to flash the board from bootloader: fis init load -r -b 0x80060000 fis create linux load -r -b %{FREEMEMLO} fis create rootfs fis load -l linux exec -c "" For RouterStations use TFTP recovery procedure.
